This invention rela-tes to stalk cutters, and its general object is toprovide' a rotary stalk cutter including cutting blades secured in pairslongitudinally of the cylinder and arranged a considerable distanceapart so as to be subjected to a chopping action for cutting stalks,weeds and the like accordingly with the result that such material willbe thoroughly cut in a single operation.

A further object of the invention is to provide a cutter of thecharacter set forth that is extremely simple in construction,inexpensive to manufacture and eiicient in operation in service.

This invention also consists in ce1 tain other iatures ot constructionand in the combination and arrangement of the several parts, to behereinafter fully described.l illustrated in the accompanying drawingsand speciiically pointed out in the appended claim.

ln describing my invention in detailj reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure lis a top plan view of the cutter forming the subject matter of thepresent invention.

-Figure 2 is side elevation thereof,

Figure 3 is a sectional view taken approximately on line 3 3 of Figure llooking in the direction ot the arrows.

Figure 4 is a fragmentary Ysectional View taken through one end of thecylinder and showing one of the end shafts of the cutter together withits blades, in elevation.

Figure 5 is a sectional view taken on line or" Figure l, looking in thedirection of the arrows. y

Referring to the drawings in detail, it will be noted that the chopperincludes a body trame made up of side strips l with elongated front andrear strips 2 and 3 arranged in superposed pairs, as best shown inFigure 3 oitl the drawings. The front and rear strips are secured attheir ends to the side strips l and a tongue extends centrally of theframe with its rear portion secured between the pairs of the front andrear strips. Converging braces l have their adjacent ends secured uponopposite sides of the tongue while their rear ends are secured betweenthe rear strips.

Filler pieces 5 are disposed between the ends of the lowermost front andrear strips and underlie the side strips as best shown in Figure 2 anddepending from these ller strips and secured thereto as well as the sidestrips l through the medium of bolt and nut connections 6 are dependingside members 7 having their front and rear edges disposed at aninclination toward each other as clearly shown in Figure 2.

The cutter includes a hollow cylinder S having secured in its ends solidcores 9 which have secured therein and extending centrally therefromstub axles l0 arranged for rotation in bearings formed in the sidemembers 7.

Secured to the cylinder in equi-distantly spaced relation with respectto each other are cutting blades ll which are arranged a. considerabledistance apart as best shown in Figure of the drawings for a purposewhich will be presently apparent. The cutting blades have their endsterminating adjacent the ends of the cylinder and are secured to thecylinder by brackets 12 which are termed in a manner whereby the bladesare secured in pairs by bolt and nut connections 139 the blades beingfined to ears le by the bolt and nut connections while the remainingportions oi" the brackets are secured to the cylinder by bolt and nutconnections l5. rhe cylinder is provided with slots l arranger wherebyaccess may be had to the nuts oi'l the bolt and nut connections l5 whenit is desired to secure or remove the blades from the cylinder as willbe apparent.

The tongue is provided with a link or other like means l? wherebypropelling means can be secured to the cutter for drawing the same.

F rom the above description and disclosure of the drawings, it will beobvious that l have provided a cutter which will easily cut stalks,weeds and like material in a thorough manner due to the arrangement ofthe blades which are disposed a considerable distance apart on thecylinder with the result during the rotation of the cylinder the bladeswill be given a chopping action.

What I claim s:-

A"cutter of the character described comprising a cylinder having coresdisposed Within the ends thereof, stub axles Carried by and projectingfrom the cores, brackets secured upon the outer surface of the Cylinder,ears projecting from the opposed side portions of the bracket members inrghtaugularly disposed relation, and blades having fixed con f neet-ionwith the ears.

In testimony whereof I affix my signature.

JAY ROBBINS.
